Our People
Seth A. Stambaugh, M.Ed.
Founder and Owner
Seth A. Stambaugh grew up in Placitas, New Mexico riding his bike, going to school, and with a natural passion for learning. He always possessed a deep ability to concentrate, which aided him in his creative and educational endeavors. During his childhood, Seth attended both Montessori and traditional elementary schools before matriculating at Albuquerque Academy in 1998 for middle and high school. During his time there, he discovered that his passion for education had a deeper root than in simply learning; it extended to helping others learn as well.
In seventh grade, Seth began volunteering as a teacher’s assistant at local elementary schools. In high school, he tutored students who were inmates at the Camino Nuevo Youth Center in Albuquerque, New Mexico. During his senior year, he chose to complete his “Senior Project” by becoming an intern teacher’s assistant at Cottonwood Montessori in Corrales, New Mexico.
After graduating from the Academy with a cumulative 4.24 GPA in 2005, Seth decided to move to Portland, Oregon, to continue his educational pursuits at Lewis and Clark College. He studied English and Sociology before pursuing a graduate degree in education at Lewis and Clark Graduate School of Education and Counseling. He received his Master’s Degree in Education (M.Ed.) with a 4.0 GPA and returned to New Mexico. Continuing his education, he enrolled in Montessori Elementary Teacher training at The Montessori Education Center of the Rockies in Boulder, Colorado, receiving his Montessori Teaching Certification from the American Montessori Society. He gained experience working in both public and private schools as a state certified teacher while also tutoring students one-on-one in his spare time.
​
After ten years working as a schoolteacher, Seth decided to create Piñon Tutoring. He believes one-on-one tutoring is the most effective way for students to gain knowledge, hone critical thinking skills, identify core values, and develop integrity. He embraces the idea that learning is not just about developing competence in subject areas, but also about developing confidence, life skills, and identity.
In his free time, Seth enjoys working on home projects, cooking, writing, and spending time with his dog and two cats.

Kelly Dunn, MAPL
Contract Tutor, 6th-College Spanish and Writing Expert
Kelly was born and raised in Baltimore, Maryland. At an early age he discovered his passion for language and writing and would later go on to study both Spanish language and Linguistics at the undergraduate level. It was here that he first began tutoring language and assisting with ongoing research into second language acquisition as well as language documentation at the University of Maryland Baltimore County. During this time, he also worked closely with the Pro Bono Resource Center of Maryland as a volunteer interpreter. Ultimately, these experiences would lead him to pursue further graduate study, focusing on the social aspects of language change and development.
​
Inspired by the linguistic and cultural diversity of the Southwest, Kelly moved to Albuquerque in 2018, where he completed his Master’s Degree in Linguistics at the University of New Mexico. While in the program, he had the opportunity to work as an instructor, teaching both beginning and advanced language levels in the department of Spanish and Portuguese. Looking to develop further as an educator, he also took on additional work as both a writing and language tutor and online learning assistant at the Center for Academic Program Support, receiving his tutor certification from the College Reading and Learning Association.
Having occupied a variety of roles within education, Kelly takes a holistic approach to language learning, placing equal emphasis on developing listening, reading, writing, and speaking skills. He recognizes the difficulties and challenges that learners face when exposed to a foreign language for the first time and believes that a structured approach guided by compassion and flexibility is key to success. In many ways, he views tutoring as an ideal opportunity to meet learners at their level and help them to both develop and apply their skills beyond the instructional setting.
In his spare time, Kelly enjoys cooking, gardening, reading, and caring for the fish he and his partner keep together.

Kristen Tanski, M.Ed.
Contract Tutor, K-5th All Subjects Expert, Special Education Expert
Kristen is a special education teacher with over 5 years of teaching experience. Kristen came to education through an unusual path. While growing up in Connecticut, Kristen fell in love with Kung Fu and began teaching kids classes at her dojo while still in high school. After starting her own school and almost ten years as a martial arts instructor, Kristen realized the highlight of her job was the teaching, not the business or Kung Fu, so she left martial arts to pursue teaching full time. While getting a master’s degree and teaching certification in elementary education and a teaching English as a Second Language certification from Fairfield University, Kristen worked in many positions in the Connecticut public schools, including as a substitute, educational assistant for special needs students, and an English as a Second Language tutor.
In 2018, Kristen moved to Honolulu, Hawaii for more sun, more beaches, and more education. Kristen received her Special Education certificate and learned the Orton-Gillingham phonics method as she focused her career on special education and literacy.

In 2024, Kristen and her family moved to Albuquerque where she taught at the May Center as a literacy teacher with students with different learning disabilities like dyslexia and ADHD. Throughout her career, Kristen has lived by the philosophy she learned as a martial arts instructor that learning is not a one size fits all experience. It is a teacher’s job to understand each student as an individual and find ways to help them to be successful.
